about switching roles in run-time without disconnecting from the db, there's
a static provision: the SQL standard caters for roles that can be granted to
roles. So, this is poor's man way to have several roles assigned. The
drawback is obviously that you have to create the new role in advance and
grant to it the already present roles you want. At least you have
I've read the code and there's a little stub (with a comment) in DYN where
code can be written for this purpose. After that, I guess we would need to
change grant.e to check permissions in run-time... this is more
intimidating, since the code has a comment saying "do not change the order
of these clauses" or something alike.
